This is a pair of adult Clark's Anemonefish (A. clarkii),
peeking from the shelter of their anemone (probably H. crispa). This was taken
with a Nikonos close-up attachment and a 28mm lens. This was a difficult shot, since both
fish are constantly moving around to avoid the camera. Both happened to be ideally
positioned for a rare moment when I clicked the shutter.
